1 Core network aspects

7.2.1 Benefits

The user of sensor data benefits from DAN, due to its simple method of data uploading and access. The sensor
device does not need to specify the final destination of the sensor data, but simply specifies the name or ID
of the sensor data and sends it to a DAN element using broadcast, etc. The user of the sensor data also does
not need to specify the location or address of the DAN element where the sensor data are stored, but simply
specifies the name of the data. This greatly simplifies the design of sensor devices and applications regarding
data communication.

The service provider or the network operator benefits from DAN due to its efficient mechanism for uploading
sensor data. The data are collected at a DAN element close to the sensor device, which reduces transmission
delay and uplink traffic. The sensor device needs to wait for a minimal transmission time to upload its sensor
data. The sensor device also does not need to manage an end-to-end communication session to data
consumers, which reduces the burden on the sensor device for data communication.

The service provider or the network operator also benefits from DAN, due to its simple management of
mobility. The sensor device can be moved to another location without any reconfiguration at the DAN layer.
The user can access sensor data without reconfiguration of location or address, which reduces sensor
network management costs where sensor numbers are large.

7.3 Vehicular networking
This service scenario involves vehicles (such as automated cars and trains) that are connected to the network
and DAN elements collecting vehicle-related data generated from in-vehicle devices. In-vehicle devices can
be either a navigation system including smartphones attached to the vehicle or an embedded system such
as on-board wireless system attached to a controller area network (CAN). Vehicle-related data include
location information (e.g., current location, destination location), driving information (e.g., steering, velocity,
acceleration, braking) or states information (e.g., fuel level, maintenance information).
Figure 7-5 depicts a sample scenario for vehicular networking using DAN.
